Structure and mechanism of the ER-based glucosyltransferase ALG6

In eukaryotic protein N-glycosylation, a series of glycosyltransferases catalyse the biosynthesis of a dolichylpyrophosphate-linked oligosaccharide before its transfer onto acceptor proteins1. The final seven steps occur in the lumen of the endoplasmic reticulum (ER) and require dolichylphosphate-activated mannose and glucose as donor substrates2. The responsible enzymes?ALG3, ALG9, ALG12, ALG6, ALG8 and ALG10?are glycosyltransferases of the C-superfamily (GT-Cs), which are loosely defined as containing membrane-spanning helices and processing an isoprenoid-linked carbohydrate donor substrate3,4. Here we present the cryo-electron microscopy structure of yeast ALG6 at 3.0?A resolution, which reveals a previously undescribed transmembrane protein fold. Comparison with reported GT-C structures suggests that GT-C enzymes contain a modular architecture with a conserved module and a variable module, each with distinct functional roles. We used synthetic analogues of dolichylphosphate-linked and dolichylpyrophosphate-linked sugars and enzymatic glycan extension to generate donor and acceptor substrates using purified enzymes of the ALG pathway to recapitulate the activity of ALG6 in vitro. A second cryo-electron microscopy structure of ALG6 bound to an analogue of dolichylphosphate-glucose at 3.9?A resolution revealed the active site of the enzyme. Functional analysis of ALG6 variants identified a catalytic aspartate residue that probably acts as a general base. This residue is conserved in the GT-C superfamily. Our results define the architecture of ER-luminal GT-C enzymes and provide a structural basis for understanding their catalytic mechanisms.

Synthesis of Glycosyl Chlorides and Bromides by Chelation Assisted Activation of Picolinic Esters under Mild Neutral Conditions

A general method has been developed for the formation of glycosyl chlorides and bromides from picolinic esters under mild and neutral conditions. Benchtop stable picolinic esters are activated by a copper(II) halide species to afford the corresponding products in high yields with a traceless leaving group. Rare beta glycosyl chlorides are accessible via this route through neighboring group participation. Additionally, glycosyl chlorides with labile protecting groups previously not easily accessible can be prepared.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 10343-06-3 is helpful to your research., Reference of 10343-06-3

Synergistic solvent effect in 1,2-cis-glycoside formation

Construction of three continuous 1,2-cis-alpha-glucosidic linkages was achieved in optimized solvent system. High-throughput optimization was conducted, by using substrates protected by perdeuterated benzyl (Bn-d7) groups. It enabled facile evaluation of yield and stereoselectivity with 1H NMR and MALDI-TOF MS, respectively. We found that CHCl3 and ethereal solvent had a synergetic effect to enhance the alpha-selectivity. The optimized solvent systems in CHCl3/CPME and CHCl3/Et2O were applied to the linear synthesis of Glcalpha1?2Glcalpha1?3Glcalpha1?3Man (Glc3Man1), which was achieved in 86% overall stereoselectivity.
